Inputs
Impedance: 20 kΩ, Balanced
Level:
+4 dBu nominal, +26 dBu maximum
Outputs
Note: 50Ω/50Ω designates 50Ω resistors in each leg of an output.
Monitor Amplifier Outputs:
Impedance: 50Ω/50Ω Single ended
Level:
–2 dBu nominal, +20 dBu maximum for loads > 2.5 kΩ
Nominal level can be trimmed from -2 dBu to -22 dBu in .1 dB steps
Wide Send, 4/2/4 Send, Meter Outputs:
Impedance: 50Ω/50Ω Balanced
Level:
+4 dBu nominal, +26 dBu maximum for loads > 5 kΩ
Downmix Outputs:
Impedance: 50Ω/50Ω Balanced,
Level:
+4 dBu nominal, +26 dBu maximum for loads > 5 kΩ
A single Wide Inputs input to Downmix out will reflect a 3 dB loss to account for
Downmix summing bus build, plus any Downmix coefficients for that input channel
Frequency Response
Bandwidth: 20 Hz to 20 kHz, < .3 dB error for all audio paths
Distortion
THD+N:
≤ .01%, 20 Hz – 20 kHz, maximum rated level for all audio paths
Crosstalk and Leakage
Crosstalk: Between signal paths operating at maximum rated level
> -100 dB at 1 kHz maximum rated level
> -80 dB at 10 kHz maximum rated level
Leakage:
From unselected sources operating at maximum rated level
> -100 dB at 1 kHz
> -80 dB at 10 kHz
Residual Noise
Speaker Outputs
Trim @ 0: ≥ 110 dB below signal that produces maximum output level
+24 dBu in = +18 dBu out, SPL set to maximum
≥ 90 dB below signal that produces nominal SPL level
+4 dBu in = –12 dBu out, SPL set 10 dB below maximum
Trim @ –20: ≥ 100 dB below the signal to produce maximum SPL
+24 dBu in = –2 dBu out, SPL set to maximum
≥ 80 dB below signal that produces nominal SPL level
+4 dBu in = –32 dBu out, SPL set 10 dB below maximum
Sends and Other Outputs
Residual:
≥ 120 dB below maximum output level
